Update production data from development environment C6

Hi guys,

I am using C6 and one of my struggles is that I want to update some production data without needing to create a function and transfer this to the production environment to update some data.

Little bit of elaboration:

I have invoice lines in Creator Production environment. These invoice lines are synced from Books to Creator. However, I have added some fields in Books, so I would like to update my history in the Creator Production environment. I would like to do this by creating a function in the Development environment and triggering this function once and then delete it again.

Is this possible using the standard Creator deluge functions? So e.g. Invoice_line.Category = "Banana", or is this only possible by using the Creator API to fetch each record and update it through the API as well?

Thanks.
